Road Widening

The Arizona Department of Transportation is soliciting sealed bids for road widening on Thornton Road in Casa Grande, Pinal County, with bids due July 17, 2026 at 11:00 a.m. Mountain Standard Time. The project is federally aided and subject to Davis-Bacon wage determinations.

The scope includes constructing an additional northbound through lane on Thornton Road from SR-84 to Peters Road, reconstructing the southern portion, installing new curb and gutter with raised medians, widening the north portion, installing new lighting along the southern portion, making minor drainage improvements, and completing signing and pavement marking work. The contract period allows 365 calendar days for completion.

The Department has programmed $4.97 million for this work. Bidders must be prequalified by the Department and included on the project Plansholder List as a Prime. Electronic bidding is required; Prime Contractor approval requests must be received at least five working days prior to bid opening. Each bidder must provide an electronic proposal guaranty of 10 percent of the bid amount payable to the Arizona Department of Transportation. The awarded contractor will execute Performance and Payment Bonds, each in 100 percent of the bid amount, along with an Insurance Certificate and Contract Agreement.

All contractors, subcontractors, and DBEs must register in the Arizona Unified Transportation Registration and Certification System (AZ UTRACS). The Department will not set DBE contract goals during the current transition period as the Arizona Unified Certification Program completes recertification under revised federal standards effective October 3, 2025; however, contractors are encouraged to employ DBE neutral efforts. Bidders must submit a Bidders/Proposers List confirmation email to the Business Engagement and Compliance Office no later than 4:00 p.m. on the fifth calendar day following bid opening.
